RES ONATOR Filed July 15, 1928 Patented Oct. 14, 1930 UNITED STATES WILLIAM ZAUNER, OF CLEVELAND, OHIO RESONATOR Application filed July 13,

This invention relates to musical instruments and the general object of the invention is to provide a resonator for stringed instruments, that materially im n'oves the 5 tone qualities thereof as well as gives the tone maximum depth and greatly increases its resonance.

A further object of the invention is to provide a resonator for stringed instruments that is extremely simple in construction, in-

expensive to manufacture and efficient in operation and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is an enlarged fragmentary longitudinal sectional view taken through the body of aukulele and showing the application of my resonator thereto.

Figure 2 is a bottom plan view with the rear plate of the ukulele removed.

Figure 3 is a sectional view taken approximately on line 33 of Figure 2, looking in the direction of the arrows.

deferring to the drawings in detail, it will be noted that I have illustrated my resonator as being applied to a ukulele, but I want it understood that it can be applied to any stringed instrun'ient without departing from the spirit of the invention. The resonator includes a pair of side walls indicated respectively by the reference numerals 1 and 2 and these side walls are disposed in converging relation with respect to each other when in secured position to the under-surface of the front plate of the ukulele body as best shown in Figure 3 of the drawings.

The side walls are substantially triangle shape in formation, with the apex ends there of cut-away and disposed in contacting engagement with the base block 3 of the body.

1928. Serial No. 292,430.

The straight edges of the side walls are fixed to the front plate in a manner to be disposed upon the opposite sides of the string bridge 4, while secured to the inclined or free edges of the side walls 1 and 2 is a sheet of relatively thin material 5. The side walls and sheet of material 5 are formed from wood and it will be noted upon inspection of Fig ure 3, that the side walls are much thicker than the sheet of material 5 which is formed with inclined side edges to follow the arrangement of the side walls, with the result the resonator is of substantially funnel formation with its large enddirected toward the sound openin of the instrument.

From the above description and disclosure of the drawings it will be obvious that I have provided a. resonator for a stringed instrument that will deepen its tone quality and greatly increase the resonance thereof.

it is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

lVhat I claim is:

A musical stringed instrument, in combination with side walls having upper flat edges secured to the under surface of the front plate of the body of the instrument, said walls being arranged in converging relation with respect to each other upon opposite sides of the string bridge of the instrument and having their adjacent ends cut-away and dis posed in contacting engagement with the base blcJk of the body of the ii'istrument. downwardly inclined lower edges for said side walls. a sheet of material secured to the downwardly inclined lower edges and cooperating with said side walls to present a substantially funnel formation with the enlarged end thereof directed toward the sound opening of the instrument, and said sheet of material being relatively thinner than said side walls.

In testimony whereof I aflix my signature.

WILLIAM ZAUNER.
